ELECTRIC-RAILWAY VEHICLE.

Specification of Letters Patent.

Application filed September 8, 1908.

Patented May 30, 1911. Serial No. 452,095.

To all whom it may concern:

Be it known that I, Gnonen M. EATON, a citizen of the United States, anda resident of Wilkinsburg, in the county of Allegheny and State ofPennsylvania, have invented a new and useful Improvement in Electric-Railway Vehicles, of which the following is a specification.

My invention relates to electric railway vehicles, and particularly tomeans for operatively connecting the propelling motors to the partsdriven thereby.

The object of my invention is to so construct and arrange the parts of avehicle that the geared driving connections between the propelling motorand the driving wheels may be placed outside of the wheels, in orderthat the motor may occupy substantially all of the space between thedriving wheels, and thus permit of the employment of larger motorsthan'could otherwise be utilized.

Figure 1 of the accompanying drawings is a view, in side elevation, of aportion of a locomotive embodying my invention. Fig. 2 is a View, in endelevation and in vertical section, of some of the parts shown in Fig. 1,and Fig. 3 is a perspective view of an end bracket of the propellingmotor of the vehicle.

Located between, and largely above the main axles 1 and 2 of an electriclocomotive having driving wheels 3, is a motor 4 that extends betweenthe wheels upon each axle and is provided upon each side, near itsbottom, with bearings 5 for quills 6 that loosely surround the drivingaxles.

Bearings 7 for the motor shaft 8 are mounted upon a main frame 9 for thelocomotive that is resiliently supported upon journal bearings 10 by anysuitable means, such as that illustrated, which is deemed unnecessary todescribe in detail since it constitutes no part of the presentinvention.

Mounted upon the shaft 8, and near its extremities, are gear wheels 11that are located outside of the driving wheels 3, the said gear wheelsmeshing with other gear wheels 12 and 13 of annular form and having arms14 that extend inwardly between the spokes 15 of the driving wheels andare bolted, or otherwise suitably secured, to flanges 16 at theextremities of the quills 6. The gear Wheels thus serve to operativelyconnect the motor shaft 8 to the quills 6,

while the bearings 5 maintain the motor and the quills in fixedrelations with respect to each other, oscillations or variations in thepositions of the drivin axles within the quills 6 being permittedbecause they are loosely surrounded by the quills. The arms 14 areprovided with extensions 17 of annular form that embrace and grip themiddle portions of helical compression springs 18 which constitute partsof resilient operative connections between the driving wheels and thegear wheels 12 or quills 6, such connections being set forth more fullyin appli cation, Serial No. 426,344, filed April 10, 1908, by John E.Webster and assigned to the WVestinghouse Electric & ManufacturingCompany.

It will be noted that the gear wheels 11, 12, and-13, constituting aportion ,of the means for operatively connecting the motor to thedriving wheels, are located outside of the driving wheels, thus leavingall of the 7 space between the wheels to be occupied by the motor,which, obviously, may be of larger size than would otherwise bepermitted.

I claim as my invention:

1. In an electric railway vehicle, the com bination with two parallelaxles having driving wheels, and quills surrounding the axles andyieldingly connected to the wheels, of a motor mounted between the axlesand extending between the driving wheels, and operative connectionsbetween the motor and the quills, said connections comprising gearwheels located outside of the driving wheels.

2. In an electric railway vehicle, the combination with a pair of axleshaving driving wheels, of a motor located between said axles, andoperative connections between the motor and both axles, said connectionscomprising gear wheels located outside of the driving wheels andyielding connections be tween the gear wheels and the driving wheels.

3. In an electric railway vehicle, the combination with an axle havingdriving wheels, and a quill surrounding the axle, of a motor locatedbetween the driving wheels and having bearings upon the quill,intermeshing gear wheels connected respectively to the motor and to thequill, and means operatively and resiliently connecting the quill to thedriving wheels.

4. In an electric railway vehicle, the combination with two parallelaxles having driv ing Wheels, and quills surrounding the axles, of amotor mounted between the axles and extending between the drivingwheels, bearings for the motor upon the quills, a gear Wheel actuated bythe motor and located out side the driving wheels, other gear wheelsmeshing therewith and connected respectively to the quills, and meansoperatively and resiliently connecting the quill 'to the 10 drivingwheels. 7 r

In testimony whereof, I have hereunto subscribed my name this 31st dayof August, 1908.
